To allfwhomitmag/concern.' l'

Be it'kuown that I, GASTON W. MONTGOM- nnr, a citizen of the UnitedStates, residingE at Toronto, county of York, Province' of Ontario,Canada, have invented. a certain new and 'useful Improvement inCooktores, and declare the following to be a full, clear, and exactdescription of the same, such as will enable others skilled in the artto which it pertains to make and use the samefreference beinghad to theaccolti'-l panying drawings, which form a part of this specification.

This invention-relatesto stoves for .cookin which both the heat fromargas burner and steam is used to cook with.v y

A still further feature is the transfer of the vapors 'arising fromthefoodsand also the steam to the combustion chamber of.the\

gas burner. l l I.

In the drawings: Figure 1, is a vertical section on the line A--A ofFig. 2, a party of the ovens being left in elevation to'show'. thedoors. Fig. 2, is a vertical section von the line B-B of Figpl.

A cabinet a is formed preferably of metal and is lined withheat-insulating material, such as asbestos, b. I n my preferred form ofconstruction I support two sheet metal the oven c above the oven d.AEach oven has a door' e which opens downward.y The door e horizontallywhen it is open. Access may behad to each oven through the-heat--insulated closures f of the cabinet. .These closures have a bevelediitwith the openings. in the cabinet to insuretight-ness when closed.

Two water tanks gare supported in the interior of the cabinet, oneadjacent to each oven. -These tanks are fastened to a beveled edgeclosureJt of the cabinet. The beveled edgeV ts 'into a correspondinglybeveled opening -that insures an, air-tight. ft. A drainage cock z'leads from the tankthrough the closure. A nipple 7 protrudes from onetrudes from each water tank so that when the water tanks are placedtheir nipples slide into the over-nipplesto form a pas sage between theoven and water tank, The

nipples stay bolts Z that connect with the sides of the cabinet oppositethe sides having the nipples vand by the pipinghereiriafteli described.1

'A burner is supported; inthe 'cabinet-.by l

legs mi It is formed into three chambers, a gas chamber n, and two airchambers; o,

one above and the other belowthe. gas chamber. The principal source of'fuel for the burner enters the cabinetthrough' the pipe p that leads tothe gas chamber n. This pipe-.ju is-controlled on the routside of the.

Acabine-t bythe vai:e q: An air pipe 1' leads from the exterior of thecabinet up to a point above the burner Where -it `divides and..the ytwobranches lead across the burner slightly above' it toapoint beyond therear wall of the zov'ens, thenhorizontally to the rear of,

the ovens near the bottom. TheV branch 's leads into 'the oven d. vThebranch t leads .l

into' the oven On the opposite sides of the ovens lthe pipe u connectswith each oven. and leads'th'erefroni into eachgair chamber o v oit theburner/by branches.

A stack m' is located at the top of the The Vmode-ofoperation is asfollows The gas maybe turned on and the burner ignited by opening theclosure s of the cabinet. This heats the air inthe cabinet and it risesand'eseapes through the stack a. More air to Vtake its" place is4 drawnthrough the air piper and the branches -s andt of the same intojtheovens c .and d. -While passing through thebranches s and t over theburner, -the air- 1s considerably heated so that it i.passes into theovens-in a. bea-ted condition .Calculated to aid in the cooking. The airpasses through the ovens and through the pipe'uv that goes into the 'airchambers o of the burner and furnishes the necessary oxygen for thecombustion of the gas entering through. the gas pipep.. Thiscirculationthrough the ovens carries ofi' ythe'vapo'rs of the foodscooking. Some-of these vapors may be quite combustiblean'd hence fuelis added to theusual fuel supply-for a gas burner. Further, the combustion of thesevapors entirely eliminates 'the odors of cook-- ing'. When the cabinet'has lbeen sufficiently heated by the burner, the vx/aten. tanks g,

which are filled with water up to the level of the openingsofthenpplesik, begin to ovens are ppm-ted, by .theinterengaging vgive of steam.This steam enters. the ovens through the nipple connections and is drawninto the circulatory current already d escribed.. This makes a currentof steam and highly heated air. The heat of the steam l t penetratesdeeply into Vthe food stu and the heated air, while penetrating lessdeeply,

browns the food nicely. The steam in mixing with the highly heated airand passing i through the heated piping and into the air 10 chambers 0of'the burner, is superhcated. On account 'of this superheatedcondition,

when it reaches the burner, the steam is easily disassociated andfurnishes fuel for the burner.

i5 What I claim is:

`1.Ina gas cook-stove, a'heat-retainiiig chamber, an oven therein,a gasburner for heating the oven, means for supplying steam to said oven, andmeans for directing air from the outside of said heat-retainingchamber,conveying it to` where it will be pre-vheated by heat generated by thegas burner and then delivering it to said oven, and means fordirectingAthe steam .'and'heated air from said oven to the combustion chamber ofsaid burner, substantially as described. 2. In a gas cook-stove, aheat-retaining chamber, an oven contained therein, a gas burner forheating the oven, means for supn plying steam to said oven, and meansf0r`directiiig air from the outside of said heatretaining chamber,Aadjacent to the ame of said gas burner to heat the air andtlien'directing the. heated dir to the oven, and iinally directing said airand said steam Afrom said oven to the combustion chamber of said burnerfor combustion, substantially as described.

3. In a cook-stove, the combination of an 40 oven, a burner for heatingthe same, steam generating apparatus for furnishing steam to the oven,means for hea-ting air, means for directing said heated air from theoutside of the oven, through 'the oven where it picks up steam andthence directing the air,

steam and Avapors `ofthe oven to the burner for combustion,substantially as described.

4. In a cook-stove, the combination of an oven, a'burner for heating thesame, steam generating apparatus operated by the burner 'for furnishingsteam to the oven, and means for directing preheated air into the ovenwhere it picksup steam and vapors and for conducting the same' to theburner for combustion, `substantially as described.
